ktm 250sx

I had a look one of these today, and I was very impressed. It did have a sharp power band though, what could I do to make it more easier to ride on the trails? Flywheel weight, different sproket???? Do these things make much difference, are are they easy to get hold of?

Also whats it like to get gas gas parts??

[Danger]

What year SX are you talking about?

[Rupe]

it's a 1996, thanks

Flywheel weight would be your best bet. Try Bruin engineering

On the newer SX's there is a spring that you can adjust to adjust when the power valve kicks in.

Plan B flywheel weight.

[Danger]

A flywheel weight can be an option depending on the power delivery of the bike used and most MX bikes could do with one for trailriding for the less aggresive rider. There are different weights available.
Another option is to retard the timing slightly, remove the flywheel cover and turn the rotor an 1/8" in the direction that the rotor spins. Takes about 5mins and can be used in slippery conditions for smoother hook up.
John Carson imports the Steahly Flywheel weights phone 021 396 086. Usually can have them here inside 2 weeks if he does not have your one in stock.
My KTM came with alloy clutch discs and I replaced them with steel plates, fitted heavy duty tubes and even a steel rear sprocket all adding to the flywheel effect.
Correct jetting can make a big difference to your bikes power delivery. I fitted a straight taper needle to my KTM for very smooth power delivery. STD it came with a triple taper which tended to be rich down low, then lean in the midrange which resulted in a savage hit. There are JD kits that also provide smooth power for many applications. I run one on my RM.
Some pipes come with a washer where the pipe meets the cylinder. Not sure about that years KTM, but fitting three of these to my RM in place of the single washer made the power more torquey.
Different bikes need different solutions. These are just some ideas. But remember it is still a MX bike, and the suspension performance maybe more of a hinderance to you than power delivery for trail riding.
Oh yeah and going a few teeth less on the rear can also help for trailriding.

No matter what you do it will never be ideal. A flywheel weight will help but you'd be better off waiting for a trail / enduro bike. Suspension will also need looking at. How much do you want to spend on a 10 year old bike?

[Paulus]

An MXer doesn't make a great trail bike. It has a close ratio box so either 1st is too high or 5th is too low. It has a small gas tank and a limited range. It has too firm spring rates and damping for trail use. It usually has a higher seat than its enduro cousins. It has a 19" rear wheel which is easier to puncture. It has a more explosive power delivery (though this can be tamed with a flywheel weight). It doesn't have a side stand. All these things can be fixed but why not just wait for an EXC to show up for sale? There's tons of them out there.

Like you I am considering a Gas Gas and have been talking to our local dealer and a few owners. Sounds like parts availability is as good as any other brand (ie has to come from overseas). Some equivalent parts from Honda, Kawasaki and KTM will seemingly fit in various areas. It would also seem that the bikes are actually very reliable so hopefully won't need a lot of bits thrown at them. Resale value is pretty low on the Gas Gas and my local KTM dealer warned that he wouldn't trade one (like trading ever gets you a good price anyway).

EXC out of the box ......Awesome!

Hey a mate of mine has an old CR that he mihgt part with. I'll find out.

Think I've sorted out a bike now, but I'll have to wait till later in the week before it's 100%. Hey Cheese any ideas where's cheap to go on the shore to kit myself out with all the bits I'll need, helmet, 2stroke oil ,etc?

[cheese]

On the shore you can go to cycle treads, they are ok on prices.

I'd reccommend going to MotoMail outlet store. THey have some really good deals.

Now when shopping for your bits, with a helmet, try to get one with a removable liner. It helps so much then you need to clean it!

As for oil, I've used Motul and got sick of paying so much for it, go for castrol TTS. It's available everywhere - like supercheap auto.

Or you could go ELF ill do it at $75 for full synthetic $50 for semi synthetic and $48 for mineral all in 4ltr pack and can be pick up for the shore from my place can do the semi and mineral in 1 ltr pack $15 semi and $11 mineral these are all under recomended retail

[cheese]

Yeah or go for bartys deal. I'll probably swap once I've used up my 8 litres of TTS.

[Rupe]

Thanks Barty that sounds good.

Anyone had much experience with thor stuff, tried on some boots today and they seemed comfy????

[cheese]

Look for metal clips adn replacable clips.

Main thing is comfort (and saftey)
